ABSTRACT:
An apparatus for applying coatings to various surface types. The apparatus includes a dispenser for holding a quantity of the coating material and a delivery tip having adjustable bristles at one end. The bristles are slidably secured in a spiral passageway formed by a helical ridge inside the delivery tip, thereby allowing the coating material to be continuously applied without the need to stop the procedure and rewet the applicator. The applicator permits accurate control of the amount of coating material applied to the surface. In this way, the surface receives neither an excessive nor an insufficient amount of the coating material. Moreover, the bristles may be pushed in to permit the coating material to be applied to a small, irregular surface, such as pits and fissures, or pulled out to permit the bristles to fan out for application to broad surface areas. Delivery of relatively viscous coating materials is made easier by providing the spiral passageway around the bristles so that the coating material does not have to flow through the bristles.
